FXLover Posted February 3, 2016 Share Posted February 3, 2016 (edited) Hi, I am not able to get correct collisions while importing alembic cylinder animation in houdini. It shows up 1 primitive count only. Can anyone help please? Thanks Edited February 3, 2016 by FXLover Quote Link to comment Share on other sites More sharing options...
cgcris Posted February 3, 2016 Share Posted February 3, 2016 try converting it to polygons first? Quote Link to comment Share on other sites More sharing options...

Navneet Arora Posted February 3, 2016 Share Posted February 3, 2016 use unpack or convert node , then use vdb from polygons. Quote Link to comment Share on other sites More sharing options...

Once that's there, call that VDB in to your DOP network using volume sampling. Quote Link to comment Share on other sites More sharing options...
Navneet Arora Posted February 4, 2016 Share Posted February 4, 2016 Check for any holes in geometry, try using a polycap and then convert it to vdb, do not forget to unpack first Quote Link to comment Share on other sites More sharing options...
